Description

Technical Field

[0001] This utility model relates to the field of CNC grinding machine tool technology, specifically to an automatic loading and unloading mechanism for a CNC grinding machine tool. Background Technology

[0002] CNC machine tools for hardware processing are CNC machine tools specifically designed for processing metal workpieces (hardware). These machine tools use CNC systems, and a CNC machine tool for hardware processing with grinding and milling functions is a type of equipment that has the ability to perform grinding and milling operations simultaneously. It is used to process hardware or other metal workpieces. This type of machine tool combines grinding and milling functions, can realize a variety of processing processes, and is suitable for processing workpieces of various shapes and sizes. When the machine tool is working, a loading and unloading mechanism is required.

[0003] The existing loading and unloading mechanisms are relatively complex in structure and unreasonable in design. They also have a low degree of automation, typically consisting of a combination of pneumatic pushing and manual clamping, which still requires manual intervention. This results in limited efficiency improvement, and the positioning accuracy depends on the worker's experience, leading to inconsistent positioning accuracy and low loading and unloading efficiency. Utility Model Content

[0006] The positioning mechanism is mainly used for positioning materials. The two ends of the positioning mechanism are respectively connected to two lifting mechanisms. The positioning mechanism includes a long plate. A lead screw is provided on the side of the long plate away from the lifting mechanism. A slider is screwed on the lead screw.

[0007] The gripping mechanism is mainly used for transferring materials. There are two gripping mechanisms, which are respectively arranged on two lifting mechanisms. Each gripping mechanism includes a base plate, on which a lead screw is provided. A sliding plate is provided on the lead screw. A servo motor is provided at one end of the lead screw to drive the lead screw to rotate.

[0008] Preferably, the support frame is a rectangular frame structure, and a lead screw is provided inside the support frame. The support platform is L-shaped, and a servo motor is screwed onto the lead screw. The side of the servo motor is connected to the support platform.

[0009] Preferably, the second slider is provided with an L-shaped support plate. One side of the support plate is connected to the second slider, and the other side extends from the bottom of the long plate to the inner side of the long plate and is equipped with a telescopic cylinder. Two L-shaped grippers are symmetrically arranged on the telescopic cylinder.

[0010] Preferably, one end of the slide plate is slidably arranged on the base plate, and the other end faces between the two lifting mechanisms. A lead screw four is provided on the slide plate, and a short plate is provided on the lead screw four.

[0011] Preferably, the slide plate is equipped with a servo motor three that drives the short plate to slide on the lead screw four, and the sliding directions of the short plate and the slide plate are perpendicular to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides an automatic loading and unloading mechanism for a CNC grinding machine tool. The loading and unloading mechanism includes a lifting mechanism, a positioning mechanism, and a gripping mechanism. The overall structure is simple and reasonably designed. The positioning mechanism connects two lifting mechanisms, and each lifting mechanism is equipped with a gripping mechanism. By sliding a support plate on a long plate, the two grippers are driven by a telescopic cylinder on the support plate to position the material. The mechanical positioning accuracy is high and the positioning accuracy is uniform.

[0015] 2. In this utility model, the rotation of the lead screw drives the slider on the side of the support platform to slide on the slide rail, thereby raising and lowering the support platform. Through the operation of the servo motors 2 and 3, the suction cup moves in the X, Y and Z directions to pick up the material placed on the support platform, thus completing the transfer of the material, improving the efficiency of loading and unloading, and achieving a high degree of automation.
